Fire Ant Towers

Those who live in areas where fire ants are active can tell you about fire ant towers. The ants will encircle a rod, stick, or tree to build a tower that is wide at the base and narrows as it goes up. You can watch this behavior on a video posted here.

Researchers at the Georgia Institute of Technology were interested in how the ants do this without crushing the ants at the bottom. What they found was that the ants form rings around the structure at the center using their sticky feet to cling to each other. The rings are all concentric, but they get smaller as the tower grows. Ants near the bottom only stay there for a short time, backing off to take a break and then climbing up to the top to rejoin the structure to keep the tower standing. These towers are temporary, but they shield the colony from outside forces.

This behavior of fire ants cannot be learned. It is certainly not the product of trial and error but is clearly programmed into the ant’s DNA. Many insect behaviors are characteristic and peculiar to a certain species of insect. These built-in skills strongly suggest that the programming was done by an intelligent Creator to enhance the survival of the insects.
